Granted: 1984-11-15
Abstract: In a cylinder block 1 of the cylinder piston arrangement a cylindrical guide sleeve 3 is inserted, in which a control piston 11 is carried, axially displaceable with a tight fit. The working chamber 8 inside the guide sleeve 3 is sealed off by an elastic sealing hose 4 bearing on this, which hose on the drive side comprises a piston member 6 and terminates at a flanged ring 7 flush with this piston member.

A lubricant introduced from outside supports the sealing hose 4 in the guide sleeve without any contact. During the working stroke the lubricant can escape through an annular gap on the drive-side end of the piston member 6 formed concentrically with a uniform interval between guide sleeve 3 and sealing hose 4. <IMAGE>

Inventor: DOBMANN GERD DIPL-PHYS DR
IPC: G01N33/38
Filed: 1985-10-02
Granted: 1986-12-18
Abstract: A method and apparatus for measuring the overlayer of a nonmagnetic material such as concrete and the diameter of steel reinforcement bars embedded therein. A steady state magnetic flux field is generated in the area of the concrete which is to be tested. A reinforcement bar embedded within the concrete generates a scatter field which is superimposed on the excitation field. By scanning the concrete surface, an amplitude locus is determined which is subtracted from an amplitude locus determined in the absence of ferromagnetic objects, whereby a difference locus is obtained. The concrete overlayer and the diameter of the steel reinforcement bar are determined from the location and magnitude of the maximum values of the difference locus with the aid of an evaluation computer.
